在所有眼外肌中,下斜肌麻痹极少见,大多数下斜肌单独麻痹是先天性的,外伤后下斜肌单独麻痹是罕见的。Brown在97例病入中仅发现3例是局部外伤引起的,其中2例是严重外伤。本文报道2例不严重的眼外伤引起单独的、短暂的下斜肌不全麻痹。例1:12岁,左眼被棒球打伤,随后发生垂直性复视5天。检查:第一眼位右眼上斜视(RHT)12~Δ,向右注视14~Δ,向左注视8~Δ,右上注视25~Δ,头向右侧倾斜RHT增大,头向左侧倾斜RHT减少,左眼下斜肌功能不足。Lancaster屏检查左眼下斜肌功能不足,其配偶肌右眼上直肌功能
In all extraocular muscles, inferior oblique muscle paralysis is rare, most of the inferior oblique muscle alone is congenital paralysis, inferior oblique muscle after trauma alone paralysis is rare. Brown only found 3 cases of local trauma in 97 cases, of which 2 were severe trauma. This article reports two cases of non-serious ocular trauma caused by a single, transient inferior oblique paralysis. Case 1: 12 years old, left eye was injured by baseball, followed by vertical diplopia 5 days. Check: the first eye on the right eye strabismus (RHT) 12 ~ Δ, right to look at 14 ~ Δ, left to watch 8 ~ Δ, right up 25 ~ Δ, head to the right tilt RHT increased head to the left Tilt RHT decreased left oblique function of the lower oblique. Lancaster screen check the left oblique function of the lower oblique, the right spine muscle function of the spleen muscle
